ANOVA Testing and Comparisions

Question 1

ANOVA testing separates the variance of the study into 2 or more components: variance due to _______ effects and ______ or _____ variance

Answer 1

treatment unexplained or error

Question 1

The ____ ratio/value means that the variance due to treatment is x amount greater than that due to random, residual error.

Answer 1

F

Question 2

In order to deterime the SS (sums of square) or the df (degrees of freedom) you can just _______ either the error or treatment from the total

Answer 2

subtract

Question 3

________ comparisons are theoretial basis for comparisions prior to the study; it does not involve testing all possible comparisions

Answer 3

planned

Question 4

In the ANOVA table if the _____ value is bigger than what is said it was/should be, then the p value is smaller than 0.05; obtain p value off of a table

Answer 4

F value
For example: F = 40.36, larger than the 6.2 the study said, p value is less than 0.001, etc.

Question 6

The ______ test is the best unplanned comparision test

Answer 6

Tukey

Question 7

In order to deteime the MS (means of squares) you ________ the SS by the df

Answer 7

divide

MS = SS/df
14.36 = 28.72/2

Question 8

_______ comparisions are effects suggested by data; many methods are available

Answer 8

unplanned

Question 9

In order to deterime “f” you ______ the MS of the treatment by the MS of the error

Answer 9

divide

f = MSt / MSe
(14.43/0.353)

Question 10

ANOVA testing will allow for analysis to test the _____ ______ of the equality of all groups

Answer 10

null hypothesis

Question 11

If the ratio of the treatment variance to the error variance is ______ then we can ______ the null hypothesis

Answer 11

large reject
